"Considering her pregnant state and emotional arc in the movie", the artist writes, "the producers felt Sandra's nightmare would have something to do with a twisted, demonic baby creature attacking her (that's as much as I could gather about the context of the scene anyway)". "It was snake-like, and I was like, 'I don't want to see it when it first happens".
